Another interior question: What should go underneath the carpet?

[White75]

When I took out the old carpet out I saw that the previous owner had put down a home carpet underlayment and a metal foil/fiberglass blanket. Neither looks like it really should be there. What should be there or more importantly, what would be the best under there. We have dual exhaust which does run under there so it can get a bit toasty so anything to protect feet and carpet would be preferred.
Thanks!

Check the archives. This topic has been discussed many times. When I replaced the carpet in my 70 I purchased a foil insulation from Lowes called I believe Dynamat and it was easy to install and made a big difference in the temp's inside the car. It is not factory correct but it works better than the matting that came from the factory.

The foil backed material might be factory. You should also find some spray on sound deadening material, depending on year, and jute backing on the carpet.

Search Reflectix and you'll find two pages, at least, with discussions about what others have done.

Dynamat, Mine went from floorboards to hot for my lady to cool to the touch. No heat hets through.

I found the reflectix stuff at Lowe's. Also found dynamat but it was a bit too expensive.
I first layed down a rubberized undercoating to add to the protection and then layed down the reflectix and it fit really well in my opinion.
